However, in recent years, as compared to the supply water of the electric vehicle, a charging place is limited due to a lack of infrastructure such as a charging station that supports electric charging.

Here, the electric vehicle may be charged with electric power in the battery of the electric vehicle using a power supply device provided in an emergency dispatch vehicle or a battery charging station when unexpected discharge or charging of the battery is required during driving. In this case, the electric vehicle can be charged with power from the emergency power supply device only when the charging coupler method is the same as the charging coupler method of the power supply device.

However, as the charging coupler of the electric vehicle is not internationally standardized as a single charging method, but is defined as a different standard for each country or manufacturer, the cable and coupler connected to the power supply device are manufactured differently for each country or manufacturer. There was a problem of deteriorating compatibility and economics.

In addition, during the contact process between the electric vehicle and the power supply device in rainy weather, the rainwater flowing into the electric wire inside the charging coupler and the cable flows through the power supply device, causing a short circuit, resulting in a fire, or electric shock when charging by rainwater. There was concern.

Moreover, as the wires are used for a long time in a high current, high temperature, and high humidity environment, there is a problem that short circuits and failures occur due to short circuits between wires provided for different purposes due to corrosion, and filling of fibrous materials provided between each wires There was a risk of fire due to burning of the member.
